LMH2120
- Linear Root Mean Square Response
- 40 dB Linear-in-V Power Detection Range
- Multi-Band Operation from 50 MHz to 6 GHz
- Lin Conformance Better than ±0.5 dB
- Highly Temperature Insensitive
- Modulation Independent Response
- Minimal Slope and Intercept Variation
- Shutdown Functionality
- Wide Supply Range from 2.7V to 5V
- Tiny 6-Bump DSBGA Package
The LMH2120 is a 40 dB Linear RMS power detector particularly suited for accurate power measurement of modulated RF signals that exhibit large peak-to-average ratios, i.e, large variations of the signal envelope. Such signals are encountered in W-CDMA and LTE cell phones. The RMS measurement topology inherently ensures a modulation insensitive measurement.
The device has an RF frequency range from 50 MHz to 6 GHz. It provides an accurate, temperature and supply insensitive, output voltage that relates linearly to the RF input power in volt. The LMH2120's excellent conformance to a linear response enables an easy integration by using slope and intercept only, reducing calibration effort significantly. The device operates with a single supply from 2.7V to 5V. The LMH2120 has an RF power detection range from -35 dBm to 5 dBm and is ideally suited for use in combination with a directional coupler. Alternatively, a resistive divider can be used.
The device is active for EN = High, otherwise it is in a low power consumption shutdown mode. To save power and prevent discharge of an external filter capacitance, the output (OUT) is high impedance during shutdown.
The LMH2120 power detector is offered in a tiny 6-bump DSBGA package.
